Understanding user experience (UX) becomes more important in a market-driven design paradigm because it helps designers uncover significant factors, such as user’s preference, usage context, product features, as well as their interrelations. Conventional means, such as questionnaire, survey and self-report with predefined questions and prompts, are used to collect information about users’ experience during various UX studies. However, such data is often limited and restricted by initial setups, and they won’t easily allow designers to identify all critical elements such as user profile, context, related product features, etc. Meanwhile, with widely accessible social media, the volume and velocity of customer-generated data are fast-increasing. While it is generally acknowledged that such data contains important elements in understanding and analyzing UX, extracting them to assist product design remains a challenging issue. In this study, how UX data underlying product design can be isolated and restored from customer online reviews is examined. A faceted conceptual model is proposed to elucidate the crucial factors of UX, which serves as an operational mechanism connecting to product design. A methodology of establishing a UX knowledge base from customer online reviews is then proposed to support UX-centered design activities, which consists of three stages, i.e., UX discovery to extract UX data from a single review, UX data integration to group similar data and UX network formalization to build up the causal dependencies among UX groups. Using a case study on smart mobile phone reviews, examples of UX data discovered are demonstrated and both customers and designers concerned key product features and usage situations are exemplified. This study explores the feasibility to discover valuable UX data as well as their relations automatically for product design and business strategic plan by analyzing a large volume of customer online data. 相似文献

For more and more firms product innovation is becoming the key to survival and future growth. Successful product innovation cannot be based only upon inspiration, fantasy and random ideas; in most firms a purposeful and systematic approach also is required. Information is a key concept in this context. As product innovation activities are very different from day-to-day activities, a special information system is required.Based on an in-depth study of a large firm, it appears that systematic innovation requires: (a) a sound business concept with future oriented strategies and policies; (b) a competent staff who master the necessary tools; (c) an efficient organization with an appropriate information system; (d) relevant methods for diversification studies and product planning; and (e) development of individual products based on systematical provision of information about user needs and proper specification of requirements.In small firms innovations are based more on the entrepreneurial approach. Such firms often demonstrate a very innovative attitude, but many of them are hampered by lack of skills in marketing and management. They also lack supporting services which can provide information about the environment.Considering the importance of small firms in economic development and social progress, they should be given support in their innovative attempts. This can be done by organizing innovation centers which arrange studies, develop courses, and give practical assistance to firms engaged in innovative work. Governments should develop policies and provide information stimulating both small and large firms to innovations that are more desirable from a social point of view. 相似文献

This paper reports our experimental investigation into the use of more realistic concepts as opposed to simple keywords for document retrieval, and reinforcement learning for improving document representations to help the retrieval of useful documents for relevant queries. The framework used for achieving this was based on the theory of Formal Concept Analysis (FCA) and Lattice Theory. Features or concepts of each document (and query), formulated according to FCA, are represented in a separate concept lattice and are weighted separately with respect to the individual documents they present. The document retrieval process is viewed as a continuous conversation between queries and documents, during which documents are allowed to learn a set of significant concepts to help their retrieval. The learning strategy used was based on relevance feedback information that makes the similarity of relevant documents stronger and non-relevant documents weaker. Test results obtained on the Cranfield collection show a significant increase in average precisions as the system learns from experience. 相似文献

设计团队知识交流与创新绩效的实证研究 总被引：1，自引：0，他引：1
产品设计在我国企业的产品创新中是一项被"遗忘"的因素,但随着设计商业价值研究的不断深入,设计作为创新元素的研究也逐渐成为热点。在现有研究成果的基础上,结合我国企业进行设计创新的实践行为,从目标、政策、手段和资源四维度构建了设计团队知识交流的一般框架,分析领先用户、高层管理政策、信息技术和资源冗余对设计团队知识交流的影响,测量知识交流对创新绩效的作用,结果发现:高层管理政策是设计团队知识交流的关键,而信息技术是重要手段;受企业传统产品创新模式的制约,领先用户与资源冗余对于提升设计团队的知识交流不具有明显的作用;研究还发现,设计团队之间有效的知识交流对增强创新绩效有重要的推动作用。 相似文献

In ad hoc querying of document collections, current approaches to ranking primarily rely on identifying the documents that contain the query terms. Methods such as query expansion, based on thesaural information or automatic feedback, are used to add further terms, and can yield significant though usually small gains in effectiveness. Another approach to adding terms, which we investigate in this paper, is to use natural language technology to annotate - and thus disambiguate - key terms by the concept they represent. Using biomedical research documents, we quantify the potential benefits of tagging users’ targeted concepts in queries and documents in domain-specific information retrieval. Our experiments, based on the TREC Genomics track data, both on passage and full-text retrieval, found no evidence that automatic concept recognition in general is of significant value for this task. Moreover, the issues raised by these results suggest that it is difficult for such disambiguation to be effective. 相似文献

Traditional index weighting approaches for information retrieval from texts depend on the term frequency based analysis of the text contents. A shortcoming of these indexing schemes, which consider only the occurrences of the terms in a document, is that they have some limitations in extracting semantically exact indexes that represent the semantic content of a document. To address this issue, we developed a new indexing formalism that considers not only the terms in a document, but also the concepts. In this approach, concept clusters are defined and a concept vector space model is proposed to represent the semantic importance degrees of lexical items and concepts within a document. Through an experiment on the TREC collection of Wall Street Journal documents, we show that the proposed method outperforms an indexing method based on term frequency (TF), especially in regard to the few highest-ranked documents. Moreover, the index term dimension was 80% lower for the proposed method than for the TF-based method, which is expected to significantly reduce the document search time in a real environment. 相似文献

通过虚拟顾客参与平台（Virtual Customer Environments, VCE）来吸引顾客参与创新、利用顾客大数据、创建顾客中心型组织成为企业的重要策略，但VCE的运行机制并未得到理论界的足够重视。本文以VCE功能为主线，将VCE分为信息展示、需求收集和深度互动三个子平台。基于刺激-机体-反应模型，分析每个子平台的运行机制。具体而言，IT环境和市场环境的发展构成VCE的运行基础，企业和顾客之间的交互关系构成VCE的运行动因，企业吸引行为和顾客参与行为构成VCE的运行过程。进一步运用内容分析法，本文检验了中国500强企业网站中VCE子平台的运行，实证研究结果支持理论模型所提出的运行机制。但同时也发现，大多数中国500强企业尚未充分构建需求收集和深度互动这两个子平台，表现为在实际运行中未能有效吸引顾客参与。本研究不仅推动了VCE理论的发展，对顾客参与理论进行了拓展，并且有助于指导企业完善VCE平台的构建，从信息技术的角度塑造顾客导向型组织，提升创新绩效。 相似文献
